[Freetype] display Kanji

[Achim Mueller]

Hi,

I want to display Text in Kanji. But since the symbols are split into 13
TTF files KANJIA.TTF to KANJIL.TTF I want to create a lookup table which
symbol is in which file. The idea was to iterate with Get_First_Char and
Get_Next_Char  over the charmaps to create this unified mapping table.
My problem is now, that this works well with e.g. VERDANA.TTF but not
with the required KANJI fonts. 

mvError = FT_Init_FreeType( &mLibrary );
if ( mvError ) {return FAILED;}
mvError = FT_New_Memory_Face( mLibrary, 
        ( const FT_Byte * ) data.cchrptr(), 
        data.length(), 0, &mFace );
if ( mvError ) {return FAILED;}
//FT_Select_Charmap( mFace, FT_ENCODING_MS_SJIS );
//FT_Select_Charmap( mFace, FT_ENCODING_UNICODE );
//FT_Select_Charmap( mFace, FT_ENCODING_MS_BIG5 );

FT_UInt FirstGlyphCode;
FT_ULong FirstCharCode = FT_Get_First_Char( mFace, &FirstGlyphCode );
cout << FirstCharCode << ",\t";
while ( FirstGlyphCode != 0 )
{                                                                
        FirstCharCode = FT_Get_Next_Char( mFace, 
                FirstCharCode, &FirstGlyphCode );        
        cout << FirstCharCode << ",\t";
};

With the KANJI fonts or even the simple 1-file KANA.TTF font the
iterator returns always 0. And a brute force lookup does it either.

FT_UInt gi = FT_Get_Char_Index( mFace, 0x4ee0 );
cout << "char 0x4ee0 -> glyph: " << gi << "\n";


Any approach is welcome.
